Section 1 - Conflict Minerals Disclosure

Item 1.01 Conflict Minerals Disclosure and Report.
Conflict Minerals Disclosure

The products covered in this report were either manufactured by Kulicke and Soffa Industries, Inc. (“K&S” or the “Company”) or contracted by the Company to be manufactured. These products may contain conflict minerals necessary to their functionality or production.
The Company focused its due diligence process on equipment and the corresponding spares that were sold during the year ended December 31, 2019 ("Covered Products"). There are certain legacy spare parts pertaining to discontinued equipment products, that constitute an insignificant portion of the Company's total sales. These have been excluded in this report as these are discontinued products and the proportion of sale of such spares will further decline in the coming years. Products and prototypes which were manufactured but not sold during the year ended December 31, 2019 are also excluded in this report.
With regard to the conflict minerals used in the products covered in this report, pursuant to Rule 13p-1 under the Securities Exchange Act ("the Rule"), the Company has conducted in good faith a reasonable country of origin inquiry ("ROCI") designed to determine whether any of the conflict minerals originated in the Democratic Republic of Congo (the “DRC”) or an adjoining country or are from recycled or scrapped sources.
The Company also undertook due diligence on the source and chain of custody of necessary conflict minerals contained in its Covered Products. Its due diligence approach was designed to conform in all material respects with the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas and the related Supplements (“OECD Guidance”).
The results of the Company’s reasonable country of origin inquiry can be found in the Company’s Conflict Minerals Report. A copy of Kulicke and Soffa Industries, Inc.’s Conflict Minerals Report is filed as Exhibit 1.01 hereto and is publicly available at We are not including the information contained on our website as a part of, or incorporating it by reference into, this filing.


Engineering team and efforts to analyze for presence of 3TG
Generally, for each of the principal products manufactured in the Company's Capital Equipment and Aftermarket Products and Services segments, our Engineering team analyzed each part in the Bill of Materials ("BOM") for presence of tantalum, tin, tungsten and gold (collectively, "3TG"). If the part did not contain 3TG, there was no further action taken and the Company's database was updated. The drawing and data sheet and material composition were examined. The following is a flow chart illustrating the approach taken by the Engineering team:
Each part was listed in a file as per the below example:
The file contains a listing of each item by part number, a description of the part, the material contained in the part, the finishing of the part, a column for each 3TG item, and a course of action. Under the "Action" column, it was noted "Yes" if the part contained 3TG or was undeterminable, and "No" if there was no presence of 3TG. If it was established that the item did contain 3TG or was undeterminable, the part was referred to the Supply Chain department for identification of the supplier of the part.
For certain subsidiaries, we sent the Responsible Business Alliance/Global e-Sustainability Initiative Conflict Minerals Reporting Template ("CMRT") to the top 98% of the suppliers in terms of total purchases.
Supply chain and efforts to determine country of origin
Generally, the Supply Chain team linked each part to the purchasing function to identify the supplier of the material, component or sub assembly. The CMRTs were forwarded to our direct suppliers ("Tier-1 suppliers") to establish the source of the 3TG for each of the items that were identified to contain 3TG. Each CMRT included questions regarding the Company’s conflict-free policy, engagement with its direct suppliers, and a listing of the smelters that the Company and its suppliers use. In addition, the template contained questions about the origin of conflict minerals included in their products, as well as the suppliers' due diligence.
The Conflict Minerals document package sent to the Company's Tier-1 suppliers contained the following:
Supplier Letter - Notification to suppliers that K&S is subject to Section 1502 of the Dodd-Frank Act, that K&S needs to comply and that their cooperation is requested.
K&S Conflict Minerals Policy
Conflict Minerals K&S Training Presentation
Standard communication documents were intended to be communicated through the Supply Chain to sub-suppliers.
Suppliers were expected to respond as follows:
Acknowledge the receipt of the request
Understand the Conflict Minerals Policy and K&S requirements


Perform due diligence on their supply chains to identify the smelter sources
Consolidate the sub-suppliers responses and integrate them into their responses
Submit the completed and signed CMRT to K&S within the requested time frame
A tracking system was implemented to monitor supplier response performance and due diligence progress. The responses received from suppliers were reviewed, and suppliers reporting 3TG items being purchased from the DRC or its adjoining countries were flagged and a risk mitigation strategy was developed for those suppliers.
The Company also holds a Supplier Day from time to time for most of its Tier-1 suppliers to, among other things, explain the requirements of the Conflict Minerals disclosure subsequent to the distribution of the standard communication documents. Presentations are made to the suppliers detailing the requirements of the Conflict Minerals rule and K&S's Conflict Minerals Policy.
We rely on our Tier-1 suppliers to provide information on the origin of the 3TG contained in components and sub-assemblies supplied to us - including the sources of 3TG that are supplied to them by their sub-suppliers. Our suppliers are required to sign, stamp and acknowledge acceptance of K&S’s supplier code of business conduct and ethics which states that K&S expects its suppliers to provide full cooperation and support in K&S’s implementation of its Conflicts Minerals Policy and compliance program.  
As we enter into new contracts, or when our existing contracts come up for renewal, we are adding clauses to require our suppliers to submit their declaration per the CMRT. Because of our size, the complexity of our products, and the depth, breadth, and constant evolution of our supply chain, it is difficult to identify sub-suppliers upstream from our direct suppliers.

Exhibit 1.01 Conflict Minerals Report
This report has been prepared by the management of Kulicke and Soffa Industries, Inc. (the “Company,” “we,” “us” or “K&S”) for the calendar year ended December 31, 2019.
A. Company Overview
We are a leading provider of semiconductor and electronic assembly solutions serving the global automotive, consumer, communications, computing and industrial markets. Founded in 1951, we pride ourselves on establishing foundations for technological advancement-creating, pioneering interconnect solutions that enable performance improvements, power efficiency, form-factor reductions and assembly excellence of current and next-generation semiconductor devices. Leveraging decades of development and process technology expertise, our expanding portfolio provides equipment solutions, aftermarket products and services supporting a comprehensive set of interconnect technologies including wire bonding, advanced packaging, lithography, and electronics assembly. Dedicated to empowering technological discovery, always, we collaborate with customers and technology partners to push the boundaries of possibility, enabling a smarter future.
We design, manufacture and sell capital equipment and tools used to assemble semiconductor devices, including integrated circuits (“ICs”), high and low powered discrete devices, light-emitting diodes (“LEDs”), and power modules. In addition, we have a portfolio of equipment that is used to assemble components onto electronic circuit boards. We also service, maintain, repair and upgrade our equipment and sell consumable aftermarket tools for our and our peer companies' equipment. Our customers primarily consist of semiconductor device manufacturers, integrated device manufacturers ("IDMs"), outsourced semiconductor assembly and test providers (“OSATs”), other electronics manufacturers and automotive electronics suppliers.
Our goal is to be the technology leader and the most competitive supplier in terms of cost and performance in each of our major product lines. Accordingly, we invest in research and engineering projects intended to enhance our position as a leader in semiconductor assembly technology. We also remain focused on our cost structure through continuous improvement and optimization of operations. Cost reduction efforts are an important part of our normal ongoing operations and are intended to generate savings without compromising overall product quality and service.
The Company operates two reportable segments consisting of: Capital Equipment and Aftermarket Products and Services ("APS").
Capital Equipment Segment
We manufacture and sell a line of ball bonders, wafer level bonders, wedge bonders, advanced packaging and electronic assembly solutions that are sold to semiconductor device manufacturers, IDMs, OSATs, other electronics manufacturers and automotive electronics suppliers.
From our due diligence analysis described in Section D, we believe that the electronic components and circuit parts in our equipment may contain tin, tantalum, tungsten and gold ("3TG").
APS Segment
In our APS segment, we manufacture and sell a variety of tools for a broad range of semiconductor packaging applications. Our principal APS segment products include capillaries, bonding wedges and dicing blades. We also offer spare parts, equipment repair, maintenance and servicing, training services, and upgrades for our equipment through our APS business segment.
Substantially all of our manufacturing operations are located in countries other than the U.S. We manufacture our ball, wedge and APAMA (Advanced Packaging with Adaptive Machine Analytics) and AT Premier bonders in Singapore, our Hybrid and Electronics Assembly products in the Netherlands, our capillaries, bonding wedges and dicing blades in China and our capillary blanks in Israel and China.
We depend on our suppliers, including sole source suppliers, for critical raw materials, components and sub-assemblies. Our products are complex and require raw materials, components and sub-assemblies having a high degree of reliability, accuracy and performance. We rely on subcontractors to manufacture many of these components and sub-assemblies.
Some of our suppliers in turn rely on sub-suppliers for some of the raw materials, components and sub-assemblies that go into the modules that the suppliers supply us.


B. Conflict Minerals Compliance Plan

Conflict Minerals Policy
As part of the Conflict Minerals Policy which the Company formulated in 2013 and continued to follow in 2019, the Company conducts the following:
Exercising the Organization for Economic Co-operation and Development ("OECD") Due Diligence Guidance for conducting inquiries into our suppliers and encouraging our suppliers to do the same.
Providing due diligence information to confirm the 3TG in our supply chain are DRC conflict-free and expecting our suppliers to do likewise.
Providing transparency in the implementation of this policy by making available reports on our progress to relevant stakeholders and the public.
The Conflict Minerals Policy is publicly available on our website at We are not including the information contained on our website as a part of, or incorporating it by reference into, this filing.
For additional information about our commitment to responsible sourcing and other human rights, see K&S 2019 Sustainability Report at
Conflict Minerals Framework and Action Plan
We have adopted the following framework in working towards our Conflict Minerals compliance as set forth in the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas and the related Supplements (“OECD Guidance”)
We took the following approach in assessing our Conflicts Minerals compliance:
We formed a multi-disciplinary Conflict Minerals team to implement our Conflict Minerals compliance process, as below:

For certain subsidiaries, we sent the Responsible Business Alliance/Global e-Sustainability Initiative Conflict Minerals Reporting Template ("CMRT") to the top 98% of the suppliers in terms of total purchases.

C. Conflict Minerals Team
In early 2013, in pursuit of achieving Conflict Minerals compliance, we formed a Conflict Minerals Committee (the "Committee"). The Committee consists of employees from the Engineering, Supply Chain, Quality, IT, Legal and Finance departments of K&S. The purpose of the Committee was to oversee the work that was required to bring K&S in conformance with Rule 13p-1 under the Securities Exchange Act (the "Rule"). Employees were assigned from different parts of the organization to support the due diligence process in identifying if 3TG were present in the Company's material purchases for the assembly of its products. The Committee regularly reviewed the due diligence progress to identify and provide resources to support the Conflict Minerals legislation requirements. The Committee appointed a multi-disciplinary due diligence team with the following responsibilities:
Analyze and identify the Bill of Materials ("BOM") of products that contain 3TG
Establish guidelines and controls to select Conflict Free Smelters ("CFS") sources for new and existing design and development of new and existing products
Supply Chain
Identify Tier-1 suppliers
Communicate with, educate and request information from affected Tier-1 suppliers and track information down the supply chain to smelter sources
Review responses, report identified "red flags" and develop risk mitigation strategy for suppliers violating sourcing policy
Track and report supplier performance or progress on 3TG due diligence
Establish systems and processes to ensure due diligence compliance
Support third-party due diligence audits in preparation of SEC reporting, if any
Respond to customer requests
Coordinate internal CM program and audits of suppliers in collaboration with Supply Chain
Provide system support for IT data collection tools to assist in the due diligence process


Enhance IT requirements and automate for future years
Interpret regulations, assist in development of policies and processes based on OECD Guidance and review of contract language
Track evolving guidelines and developments on Conflict Minerals compliance
Assist in the compilation of Form SD and the Conflict Minerals Report ("CMR")
Document and communicate K&S Conflict Minerals due diligence on the K&S website
Coordinate third-party due diligence audits on the CMR, if any
Prepare Form SD and the CMR
File Form SD and the CMR with SEC

D. Due Diligence Process
Design of Due Diligence
Our due diligence measures have been designed to conform, in all material respects, to the framework in the OECD Guidance and related supplements for 3TG.
1. Establish company management systems
We have established a management system for Conflict Minerals. Our management system includes the Committee, sponsored by our President and Chief Executive Officer, as well as executive-level representatives and a multi-disciplinary team of subject matter experts from relevant functions such as:
Supply Chain
This team is responsible for implementing our Conflict Minerals compliance strategy and is led by our VP, Global Operations and Supply Chain, who acts as the executive Conflict Minerals program manager. Senior management is briefed about the results of our due diligence efforts on a regular basis. The Conflict Minerals team remains abreast of developments concerning Conflict Minerals by way of regular participation in industry events (such as roundtable discussions and webinars) and interaction with industrial peers.
Control systems
Control systems include, but are not limited to, our Code of Conduct which outlines expected behaviors for all K&S employees.
Our suppliers are required to sign, stamp and acknowledge acceptance of K&S’s supplier code of business conduct and ethics which states that K&S expects its suppliers to provide full cooperation and support in K&S’s implementation of its Conflict Minerals Policy and compliance program. Our supplier contracts include a requirement for our suppliers to submit their declaration per the CMRT.
Supplier Engagement
With respect to the OECD requirement to strengthen engagement with suppliers, as described above, we continue to strengthen our engagement with suppliers, encouraging them to further engage with their sub-suppliers with the intentions of ultimately identifying smelter sources. Necessary training was also made available to the Tier-1 suppliers.
Feedback from this engagement has allowed us to determine the quality of responses, understand the current stage of compliance or extent of undeterminability and lastly categorize suppliers for future actions.
K&S conducts Conflict Minerals program audits regularly at identified key or red flagged 3TG suppliers to access their process and confirm that a management system is in place to provide accurate CMRT information when requested.
Violation of CM Policy
Employees and suppliers can report any violations of K&S’s policies through K&S's Whistleblower procedure. To date, we have not encountered any person that, to our knowledge, is in violation of our policy.


Maintain records
We have adopted a policy to retain relevant documentation in line with our quality management systems. K&S is ISO 9001:2015 Quality Management System certified. One of the requirements is Control of Records which defines the controls needed for the identification, storage, protection, retrieval, retention and disposition of records.
2. Identify and assess risk in the supply chain
Because of our size, the complexity of our products, and the depth, breadth, and constant evolution of our supply chain, it is difficult to identify the complete universe of sub-suppliers of our suppliers.
Our Supply Chain team identified 158 Tier-1 suppliers to which we sent the CMRT. We rely on these suppliers, whose components may contain 3TG, to provide us with information about the source of Conflict Minerals contained in the components supplied to us. Our Tier-1 suppliers are similarly reliant upon information provided by their suppliers.
The Conflict Minerals team reviewed and verified the completed templates, declarations and records from suppliers for completeness. The information received was updated in the K&S Conflict Minerals database. We also sought the services of a third-party vendor in engaging with our suppliers, follow-ups and consolidation of responses.
The following is the process that the Conflict Minerals team followed in the review and update of the information received:

The Conflict Minerals team assessed risks and made decisions for mitigation actions that needed to be taken for any non-compliance found in the reported information from suppliers for Conflict Minerals.
3. Design and implement a strategy to respond to identified risks
K&S has an approved risk management plan, through which the Conflict Minerals program is implemented, managed and monitored. Updates to this risk assessment are provided regularly to senior management.
As part of our risk management plan, and to ensure suppliers understand our expectations, we have a website ( with information, outreach events, and supplier's training. We are not including the information contained on our website as a part of, or incorporating it by reference into, this filing.
As described in our Conflict Minerals Policy, in order to fulfill our Conflict Mineral reporting obligations, we will work with any suppliers whom we have reason to believe are supplying us with 3TG from sources that may support conflict in the DRC or any adjoining country. We also attempt to establish an alternative source of 3TG in cases where the potential sources may be supporting such conflict, as provided in the OECD Guidance.


4. Carry out independent third-party audit of smelter/refiner due diligence practices
We do not typically have a direct relationship with smelters and refiners of 3TG and do not perform or direct audits of these entities within our supply chain. We rely on lists published by organizations (listed below) to evaluate the Conflict-Free Source of Origin ("CFS") status of the smelters identified by the Surveyed Suppliers.
5. Report annually on supply chain due diligence
In lieu of auditing, and in our efforts to follow the OECD Guidance, we determined that requesting supplier information on smelters and refiners using the CMRT template, and reviewing the responses received, represents the most reasonable effort to determine the mine or country of origin. Our annual CMR will be posted as part of our SEC filings and on our website.
As of the cut-off date of March 31, 2020 for responses from our Tier-1 suppliers and follow-ups, we have received responses from approximately 99% of the Surveyed Suppliers and reviewed the responses against criteria developed to determine which suppliers required further engagement. These criteria included untimely or incomplete responses as well as inconsistencies within the data reported in the template. We have worked directly with these suppliers to better understand their responses.
Responses included the names of about 382 entities listed by our suppliers as smelters or refiners. On average, our suppliers have completed about 86% of their 3TG smelter identification.
K&S checked the smelters identified by the Surveyed Suppliers against the lists published by the below organizations as CFS status:
Conflict Free Sourcing Initiative (CFSI)
Responsible Jewellery Council (RJC)
London Bullion Market Association (LBMA)
Dubai Multi Commodity Centre (DMCC)
As defined by the above organizations, “Compliant” smelters include smelters that have undergone a third party audit for having systems in place to assure sourcing of only DRC conflict free materials and are therefore identified as CFS status. "Compliant" smelters also include smelters that are only using recycled or scrap sources and smelters with sources not from the DRC. “Active” smelters are those who are in the process of being audited, or have committed to begin the audit process.
The below table summarizes certain information pertaining to smelters identified by the Surveyed Suppliers as of March 31, 2020:
Total number of smelters identified by Surveyed Suppliers
Number of “Compliant” smelters
Number of “Active” smelters
Number for which further information is needed to determine status and location (“Unclassified" smelters)
Number of "Unclassified" smelters currently reported as located in the DRC
*As part of the risk mitigation strategy, K&S will verify the source of the smelters reported to be located in the DRC and will alert the affected suppliers on the available options if any smelter is found to be sourcing from the DRC. These options include:
Supplier switching to an available alternative source;
If alternative source is not available, supplier to work towards qualifying an alternative source; or
supplier to work with Smelter to be "Compliant".


E. Future steps towards Conflict Minerals compliance
Moving forward, we intend to take the following steps with respect to our due diligence process to further mitigate any risk that any Conflict Minerals in our products could benefit armed groups in the DRC or adjoining countries:
Continue to identify suppliers whose supplies contain 3TG for all new product launches;
Continue to include Conflict Minerals flow-down clauses in new or renewed supplier contracts;
Continue to engage with suppliers frequently and direct them to training resources to increase response rate and improve compliance to the Rule;
Encourage suppliers to move their sourcing of 3TG to smelters on the Conflict Free Smelter List;
Continue to encourage our direct suppliers to purchase materials from smelters listed in the Conflict Free Smelter List; and
After providing the opportunity to change, we will disengage from those of our suppliers found to be persisting in supplying us with 3TG from sources that support conflict in the DRC or any adjoining country, by establishing an alternative source of 3TG.
We continue to work with OECD, Supply Chain Organizational Requirements ("SCOR"), industry peers and relevant trade associations to define and improve best practices and leverage over the supply chain.
